Windows 7 32 Bit - Wireless Driver Intel 7200 AGN - Code 31 Error

[shripai]

Hi,

I recently did a clean install of Windows 7 Home Premium 32 bit on my system, I backed out the data but did not back up the drivers.

Now i see that everything else seems to be working fine except the Wifi function. The wired internet works fine. I can see the various wireless network adapters like Intel 5300 AGN, Intel 5100, Intel 7200 AGN and I have also installed the latest drivers for the same. But i keep getting this Code 31 error which says "The device is not working properly because Windows cannot load the driver"

Can someone pls help me troubleshoot this. I looked around on the internet but am unable to fix this. the machine is Acer e727 and I have a 1 GB RAM.

please let me know if you need more information.

Thanks for that. I used it to install a new driver for my wifi adapter but the problem still shows. Error 31 "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"

I believe this has to do with something other than not having the driver file.

I have put in the screenshot here. If its a hardware issue, I am wondering why would it occur after the windows reinstall. The previous OS was Windows 7 32 bit as well. Also the wired internet works fine.

Download the Realtek Wireless LAN Driver ...

I installed the chipset drivers and now the realtek wireless driver. But no change in the device manager. I restarted after the chipset driver install not after the realtek. (I dont think i have the realtek adapter on my system?)

 

[maxie]

Please do another Reboot .. According to the Hardware ID you Posted you do have the realtek adapter ..

Ok i have restarted my system again. the device manager remains the same. I got to go to sleep now. Can u help me out tomorrow, pls post when you are online on this forum

 

[maxie]

No problem i will be here bright and early .. I am sure this will be easy sorted

 

[shripai]

You were right about that !!

The Realtek driver got installed now and the wireless works fine Thank u very much

Question though is why the other adapters still show a yellow mark and why wasnt this adapter showing up in device manager when i was doing 'Add Legacy Hardware'. Is there any way to see all the available adapters on your system so that we can try each one (is it through the list of hardware ids onnly?)

 

[maxie]

Most welcome glad you got the issue sorted .. If you boot from Safe Mode go to the Device Manager / View / Hidden Devices / ..

Please Post a screenshot of that ... And also the Device Manager in Normal mode with Network Adapters and USB Ports extended ...
